Report of the eleventh (and final) International Field Workshop and Symposium of Project 156: Phosphorites, organized by A. J. G. Notholt, National Correspondent, 1. Jarvis, and W. C. Burnett (Florida State University) and held at Hertford College, Oxford, England, 5–8 September, 1988. The meeting attracted over 70 delegates and speakers representing 14 countries. It consisted of 41 talks and 2 poster presentations covering a wide range of phosphorite research. A selection of papers will be published by the Geological Society as a Special Publication.
Project 156: Phosphorites is one of the most successful and probably the largest of long-term, interdisciplinary geological research projects supported by the International Geological Correlation Programme (IGCP). It owes its origin to the hypothesis by P. J. Cook, currently of the Bureau of Mineral Resources, Geology and Geophysics, Canberra, that a major Proterozoic-Cambrian phosphogenic province extends through the Asian and Australian region, perhaps comparable in size with the late Cretaceous-Eocene Tethyan province of northern Africa and the Middle East. In his Keynote Address, Dr Cook recalled that although Project 156 was established in 1977 as a research programme on Proterozoic-Cambrian phosphorites of Asia and Australia, such had been the ensuing international interest that three other Working Groups were formed within the Project, devoted respectively to an International Phosphate Resource Data Base; Young Phosphogenic Systems; and Cretaceous-Eocene Phosphorites. All four working groups had generated much research in the Project’s lifetime, a reflection also of the great scientific interest in phosphorites by virtue of their complex petrography and
